 **Temporal topology** refers to the temporal relations among time intervals or instances in different time series. They are mostly useful when sampling one STRDS with another (see [t.sample](https://grass.osgeo.org/grass-stable/manuals/t.sample.html) manual). Some examples of temporal relations are *start, equal, during, contain, overlap,* etc. See below a graphic representation of relations and sampling taken from Gebbert and Pebesma (2014). Note that A1 starts in S1, B3 is during S3, B4 equals S4, B1 overlaps S1.
